I had a surgical breast biopsy when I was 21 for a lump...and two weeks ago my OB checked another one out that I can see coming through my skin...he told me that if it were cancer it would not show through the skin...which my other one didn't show through...the one they actually were worried about. He said it is more likely an ingrown hair or a calcuum deposit since I have breasts that tend to get lumps from no where and do not go away and sometimes get larger...I'm thinking of having it looked at again...but I hope this helps!
I found this on a site:
Breast Cancer: Symptoms
Symptoms
The American Cancer Society lists the following symptoms associated with breast cancer:
• Presence of a lump or thickening in the breast;
• Swelling, dimpling, redness, or soreness of skin;
• Change in shape or appearance of the nipple; and
• Nipple discharge.
